Built from MT7-grade carbide and finished with a TiAlN coating, this tool handles demanding thread milling operations where tool life and surface finish consistency matter. It runs with a 0.276-inch cutting diameter, a 0.81-inch length of cut, and a 5\/16-inch shank diameter. With 3 right-hand flutes and 24 teeth per inch, it produces UNEF and UNF thread profiles in a single helical interpolation pass. Installation and operation require a CNC machining center with helical interpolation capability.\u003c\/p\u003e\u003cp\u003eThis thread mill is suited for production and job-shop environments where a single tool must cover multiple thread sizes within a given pitch range. Typical applications include threading bores in ferrous and non-ferrous materials where a tap would be impractical due to part geometry, hole depth, or the need to thread to the bottom of a blind bore. The 2.5-inch overall length provides clearance for most standard workholding setups. No coolant-through capability is present, so flood or mist coolant applied externally is standard practice for chip evacuation and heat management.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts internal UNEF and UNF threads from 9\/16-24 to 5\/8-24 with a single tool\u003c\/li\u003e\n\u003cli\u003eMT7-grade solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003e3 right-hand helical flutes for efficient chip flow\u003c\/li\u003e\n\u003cli\u003e24 TPI with 0.276-inch cutting diameter for precise thread geometry\u003c\/li\u003e\n\u003cli\u003e5\/16-inch shank diameter compatible with standard collet and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on CNC machining centers capable of helical interpolation.

Confirm runout is within acceptable limits before cutting, as excess runout directly affects thread quality and tool life. Program the toolpath using helical interpolation with the correct climb or conventional milling direction per the material being machined. Always verify spindle speed and feed rate against the manufacturer's cutting data for carbide thread mills in the workpiece material before running the cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: MT7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size Range\u003c\/strong\u003e: 9\/16-24 to 5\/8-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNEF, UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.276 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.81 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CARMEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MT0312C0824UN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52033496416562,"sku":"MT0312C0824UN","price":365.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40646d5e42db4904dd3057e026386d9d.jpg?v=1790021603","url":"https:\/\/voomisupply.com\/products\/carmex-mt0312c0824un-thread-mill-9-16-24-5-8-24-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
